TransitionEvent() constructor returns a newly created TransitionEvent , representing an event in relation with an transition.

句法

transitionEvent = new TransitionEvent(type, {propertyName: aPropertyName,
                                             elapsedTime  : aFloat,
                                             pseudoElement: aPseudoElementName});
